The OPA621 is stable in gains of ±2V/V or higher. This amplifier has a very low offset, fully symmetrical differential input due to its “classical” operational amplifier circuit architecture. Unlike “current-feedback” amplifier designs, the OPA621 may be used in all op amp applications requiring high speed and precision. Low noise and distortion, wide bandwidth, and high linearity make this amplifier suitable for RF and video applications. Short circuit protection is provided by an internal current-limiting circuit. The OPA621 is available in DIP and SO-8 packages. +VCC 7 Non-Inverting Input Inverting Input 3 Output Stage Current Mirror 6 Output 2 4 –VCC International Airport Industrial Park Mailing Address: PO Box 11400, Tucson, AZ 85734 Street Address: 6730 S.
